as their constitution or organization has heen de- 

 ranged, and the plants have hecome quite debilitated. 

 Young plants will do well in high temperature, say 

 from 80 to 85 degs. sunheat, with plenty of air and 

 moisture. The pine plant, when in a fruiting state, 

 and also when swelling its fruit, is not benefited in 

 the summer by a heat exceeding 90 degs. with sun ; 

 80 degs. is the best heat for swelling the fruit, and 

 although it will swell much faster in a heat of from 

 100 to 120 degs., it will not come to so great a 

 weight when grown in high temperature, as it would 

 do if kept in one not exceeding 80 degs. {Mills on 

 Fine Apple, 9.) 



This leads us to the inquiry, what is the best tem- 

 perature for the pine apple? We are always best 

 answered if the reply to our queries can be obtained 

 from nature ; and the reply, therefore, to the above 

 query shall be from observations made at Calcutta. 

 In the vicinity of that city, the yellow-fleshed pine 

 apples are high-flavoured, and commonly weigh be- 

 tween 51bs. and 61bs. ; and M. Speede, in his In- 

 dian Hand-book of Gardening," says (p. 183), that 

 by a system of very ordinary cultivation, his brother 

 grew them weighing 7ilbs. This was, of course, 

 when the plants were exposed to a climate of which 

 the following table shews the monthly averages of 

 temperature, taken at the hottest and coldest periods 

 of the 24 hours. Now, although pine apples may be
